Description

Face mask

technical field

The invention relates to protective accessories, in particular to a mask.

Background technique

Existing masks are fixed with ear-hanging wires. Both ends of the ear-hanging wires of the mask are connected to one side of the mask body. The mask provides a fixed force; therefore, if the mask is worn on the ear for a long time, it will cause the user's ear discomfort, even damage the ear cartilage, and cause pain, especially for epidemic prevention personnel and medical personnel who need to wear masks for a long time. It is necessary to wear a mask all the time during working hours, and it is not allowed to take it off to prevent infection by germs and cause the spread of the disease.

In order to solve the above problems, there is an improved mask that is fixed with a fixing belt, and the two ends of the fixing belt are respectively connected to both sides of the mask body. When in use, the fixing belt wraps around the user's head, and the fixing belt mainly touches the joint. The area behind the head has a large contact area with the head, and the force point for fixing the mask is mainly the hard bone of the head, so this kind of mask is very suitable for people who need to wear masks for a long time, even if they wear the mask for a long time There is no discomfort caused by the mask strangling the body parts.

But this improved mouth mask, while having the above-mentioned advantages, has also produced some defectives. First of all, the ear-hanging wire is used to fix the mask. Since the back of the ear is a natural concave part, the ear-hanging wire is fixed in the concave part and can be fixed by the natural limit. After the mask is fixed on the human head, it will not slip off easily. ; And the improved mouth mask, owing to be to be fixed by the abutting contact of fixing belt and the rear of human body head, promptly fixing belt is the elastic structure of elastic belt type, after fixing belt strangles the head, there is a gap between fixing belt and the head. A certain positive pressure, the positive pressure makes there is a certain frictional resistance between the fixing belt and the head, and this frictional resistance is used for the tissue fixing belt to slide up and down relative to the head (back); therefore, the realization of the fixing and anti-slip capabilities of the fixing belt , mainly comes from the frictional resistance between the fixing belt and the back of the head, and because the human head is roughly spherical, there is no natural concave fixing part, and after the fixing belt touches the spherical head, it naturally has an upward or downward direction. The tendency to slip away from the head; and the fixing belt is generally in contact with the hair on the head, and the hair is relatively smooth, and the fixing belt is easy to slide relative to the hair, especially after the head is oily, sweating, and people walk around. When the vibration is transmitted to the mask, the fixing belt is easier to slide; therefore, under the influence of various reasons, the fixing belt of the improved mask is easy to slide up and down, and even the mask is not fixed firmly or tightly, and the edge of the mask body cannot be close to the human skin. A gap that exposes the mouth and nose of the human body is generated, and even the mask is completely slipped off, and the mouth and nose of the human body are completely exposed to the dangerous environment. Therefore existing improved respirator, be badly in need of further improvement, to weaken or even eliminate the bad influence that above-mentioned defect brings.

Referring to FIGS. 1 and 2 , a mask according to an embodiment of the present invention is used to be worn on the head, and includes a mask body 100 and a first fixing belt 200 .

Cover body 100. A mask is a sanitary and anti-epidemic product. It is generally worn on the nose and mouth to filter the air entering the nose and mouth, so as to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. . The cover body 100 is the main part of the mask. When actually wearing the mask, the cover body 100 is attached to the front of the head (the area near the mouth and nose of the face) to filter the air entering the mouth and nose, and can block droplets, Objects such as dust carrying germs fall directly into the nose and mouth area. The cover body 100 can be a single-piece structure, or a multi-piece composite structure (the side edges between multiple pieces are connected to each other); the cover body 100 can also be provided with such as a fixed flexible strip for the bridge of the nose, and an inner edge leak-proof strip (for making the mouth mask The inner edge is close to the skin to prevent air from entering the mask), breathing valve and other additional accessories to enhance the various functions of the mask.

The first fixing band 200, one end of the first fixing band 200 is connected to one side of the cover body 100, the other end of the first fixing band 200 is connected to the other side of the cover body 100, and the cover body 100 is used to abut against the front of the head, The first securing strap 200 is used to abut the back of the head (so that the mask body 100 abuts the front of the head). The fixing belt mainly plays a fixing role, and is used to fix the mask on the head, while making the mask body 100 close to the front mouth and nose area of the head; when wearing the mask, the fixing belt pulls the side edge of the mask body 100 to the rear, Thereby make cover body 100 close to human facial skin as far as possible, prevent air from entering in the mouth and nose of human body from mouth mask side, make the filter function of mouth mask can't take effect. In order to be suitable for different people's head sizes and enhance the fixing ability of the fixing belt, the fixing belt is generally made of elastic material or elastic fiber, commonly used, such as rubber material, nylon material (polyamide fiber), spandex fiber and the like.

The cover body 100 and the first fixing belt 200 constitute the main part of the mask, which are the conventional settings of the mask. It should be understood that the front, back, top, bottom, and inside and outside of the mask of the present invention are based on the wearing state of the mask. The face direction of the human body is the front, and the back of the head of the human body is the rear. The rear of the body 100; the direction close to the neck of the human body is the downward direction, the direction close to the human head is the upward direction; the direction close to the human head is the inner direction, and the direction away from the human head is the outer direction. For example, the side of the cover body 100 close to human skin is the inside of the cover body 100 , and the side of the cover body 100 facing the outside is the outside of the cover body 100 .

With reference to Fig. 1, Fig. 2 and Fig. 3, in some embodiments of the present invention, also comprise the first anti-slip structure, the first anti-slip structure is arranged on the middle part of the first fixing belt 200 (first belt body 210), the first anti-slip structure The structure is used to connect the back of the head, thereby preventing the first fixing strap 200 (the first strap body 210 ) from sliding (relative to the head).

Referring to the background technical content of the present application, setting the first anti-slip structure can effectively prevent the first fixing belt 200 from sliding relative to the head, thereby avoiding the problem that the mask is not fixed firmly, not tightly, or even completely slips off.

Referring to Fig. 1, Fig. 2 and Fig. 3, in some embodiments of the present invention, the first anti-slip structure is a fixed piece 300 made of rubber, and the fixed piece 300 is used to abut against the back of the head. The fixing piece 300 is connected to the middle part of the first fixing belt 200 (the first belt body 210 ), and the fixing piece 300 is used to connect the back of the head so as to prevent the first fixing belt 200 (relative to the head) from sliding.

The fixing sheet 300 is provided with three functions. First of all, the fixing piece 300 is made of rubber. Compared with the material of the original fixing belt, it can be manufactured with a rubber material (such as coating silicon rubber) with a higher friction coefficient with the hair, thereby increasing the size of the fixing piece 300. The frictional resistance between the fixed piece 300 and the hair prevents the sliding of the fixed piece 300 and the first fixed belt 200, and compared with the thin fixed belt, the contact area between the fixed piece 300 and the hair is larger, and the contact area between the fixed piece 300 and the hair can be increased to a certain extent. Frictional resistance between hairs. Secondly, compared with the thin fixing belt, the contact area between the fixing sheet 300 and the head is larger, so the pressure (pressure) on the head bones, skin, blood vessels, etc. It is less likely to cause adverse effects on the various tissues of the head and protect the health of the user. Finally, the original fixing belt is roughly a thin strip structure, which is easy to roll up when the fixing belt slides up and down, so that the fixing belt is twisted, and the fixing belt is twisted more (more twisted circles) and more frequent, especially It is easy to affect the connection between the fixing belt and the cover body 100, so that the connection at this place breaks or falls off, so that the mask loses its fixing ability and directly falls off from the head; and the mask of the present invention is fixed by setting the fixing piece 300 The sheet 300 has a relatively large area. Even if the fixed sheet 300 slides, the fixed sheet 300 will not turn over, so that the above-mentioned accidents will not occur and the risk of disease spread will not occur.

Referring to Fig. 1, Fig. 2 and Fig. 3, in some embodiments of the present invention, a fixing hole 310 is provided at both ends of the fixing piece 300, and the first fixing belt 200 (the first belt body 210) passes through two holes in sequence. The fixing hole 310 is thus connected to the fixing piece 300 , and the first fixing belt 200 (the first belt body 210 ) and the fixing piece 300 are in interference fit.

It should be understood that when wearing a mask, the most central area of the fixing belt (or in other words, this part of the fixing belt between the two fixing holes 310) is behind the fixing piece 300, that is, the fixing belt will not be on the fixing piece. Between 300 and the head, hinder the anti-slip effect of the fixed sheet 300. Firstly, the fixing belt is connected to the fixing piece 300 through perforation, and the connection method is very simple, which is convenient for production and assembly. Secondly, the way of perforation is connected, and the connection between the fixing belt and the fixing piece 300 is more reliable. Compared with the way of bonding and hot-melt connection, the two are more difficult to separate, which is convenient for transportation, storage and use, and there is no need to worry about the glue being glued for a long time. problem after failure. Finally, the fixing belt and the fixing sheet 300 are interference fit, that is, the aperture of the fixing hole 310 is smaller than the diameter of the fixing belt, and after the fixing belt passes through the fixing hole 310, the fixing hole 310 will squeeze and hold the fixing belt (due to The fixing belt is made of rubber, so the fixing hole 310 has a certain degree of elasticity for the fixing belt to pass through, and after the thicker fixing belt passes through the thinner fixing hole 310, the fixing hole 310 will shrink spontaneously to clamp the fixing belt ), so that the fixing piece 300 has a certain fixing effect on the fixing belt, and based on this, the fixing belt has a certain function of adjusting the fixing force of the fixing belt; specifically, after wearing the mask, pull the fixing belt back The most central area, that is, the fixing strength of the fixing belt can be increased. The specific principle is that the distance between the fixing hole 310 and the side of the cover body 100 is basically unchanged, and the distance between the fixing hole 310 and the side of the cover body 100 This part of the fixing belt (its length can be called the effective length of the fixing belt), after pulling back the most central area of the fixing belt, this part of the fixing belt between the two fixing holes 310 becomes longer, and is in the fixing belt. This part of the fixing band between the hole 310 and the side of the cover body 100 is shortened, even if this part of the fixing band is stretched to a greater extent between the fixing hole 310 and the side of the cover body 100, it will make The part of the fixing belt between the fixing hole 310 and the side of the cover body 100 provides greater fixing strength; similarly, the fixing force of the fixing belt can also be adjusted in turn to reduce the fixing force.

In some embodiments of the present invention, the outer surface of the first fixing belt 200 (the first belt body 210 and the first tearing belt 220 ) is provided with an anti-skid layer.

The outer surface of the first fixing belt 200 is provided with an anti-skid layer. On the one hand, after wearing the mouth mask, a part of the first fixing belt 200 can directly contact the hair and skin on the side of the head, the back (top), so an anti-skid layer is provided. , can increase the friction resistance of the contact area, thereby playing the role of anti-slip; on the other hand, referring to the above content, the setting of the anti-slip layer can make the fixed hole 310 have greater friction between the anti-slip layer and the fixed piece 300 resistance, the effect of the fixing hole 310 squeezing and clamping the fixing belt is better. The anti-skid layer is made of a material with a large friction coefficient, such as rubber, and more specifically, it can be coated with silicon rubber.

In some embodiments of the present invention, the first anti-slip structure is a clamping part, and the clamping part is used to clamp the hair on the back of the head. The clamping part is connected to the middle part of the first fixing belt 200 (the first belt body 210), and the clamping part is used to clamp the hair at the back of the head, thereby preventing the first fixing belt 200 (relative to the head) from sliding.

One part of the clamping part is fixed on the fixing belt, and the other part of the clamping part is used to clamp the hair at the back of the head. The clamping part can refer to the commonly used hair clips, and can be an ordinary opening and closing clip structure, or a folding clip structure (the folding body is bent inward after the positive folding, and the folding connecting piece is closed relative to the folding body; After folding, the body of the flap is bent outwards, and the connecting piece of the flap is opened relative to the body of the flap), or other hairpin structure forms. The non-slip fixing is carried out by the clamping piece, and the fixing is more reliable.
